Verbs Master Irregular
Verbs Master - Irregular Terms of Service
These Terms govern the free electronic services connected with the Verbs Master - Irregular mobile application and its website. They are made available free of charge before the agreement is concluded in a form that can be viewed, saved and printed.
1. Service Provider
The service provider is Grzegorz Kniażuk, a sole trader operating under the business name Grzegorz Kniażuk Software Development, ul. Garbarska 18A/98, 20-340 Lublin, Poland, Tax Identification Number (NIP): 9462761962, National Business Registry Number (REGON): 543548683 (the “Provider”). The Provider may be contacted electronically at kontakt@kniazuk.dev.
2. Definitions and scope
“Application” means Verbs Master - Irregular distributed through a supported application store. “Website” means the Application website, including the Privacy Policy and Terms pages. “User” means a person using the Application or Website. These Terms cover services supplied directly by the Provider; use of an application store, operating system or another third-party service is also governed by that provider’s own terms.
3. Services
The Application enables Users to browse and search English irregular verbs, play pronunciation using voices available locally on the device, use built-in flashcard decks, create custom local decks, and adjust study and appearance settings. The Website presents information about the Application and provides legal documents. The Application does not require an account, contain advertising, in-app purchases or subscriptions, and is provided free of charge. The Provider does not require personal data as payment. Charges imposed by a telecommunications operator or store provider for internet or device use are not Provider charges.
4. Technical requirements
The Application requires a compatible device, a supported operating-system version and sufficient storage. Internet access is required to download and update the Application and to open legal documents and external pages. Core study features work offline if a suitable system voice is available on the device. The Website requires internet access and a current browser.
5. Electronic-service risks
Electronic services involve ordinary risks such as malware, system vulnerabilities, device loss, unauthorized access, and loss of locally stored data. Users should keep the system and Application updated, use legitimate software, protect the device with an access lock, and avoid keeping the only copy of irreplaceable content in the Application.
6. Formation and duration
The Website agreement is concluded for a single session when the page is opened and ends when the User leaves it. The Application agreement is concluded for an indefinite period after the Terms are made available, the acceptance checkbox is selected, and the button to enter the Application is chosen. The accepted Terms version and acceptance time are stored only on the device and are not remotely accessible to the Provider. A person without full legal capacity should use the Application with the consent or assistance of a legal representative to the extent required by applicable law.
7. Acceptable use
Users may use the Application and Website in accordance with the law, these Terms, their intended purpose, and the relevant store rules. It is prohibited to provide unlawful content, infringe the rights of others, disrupt the services, circumvent security measures, distribute malicious code, or attempt unauthorized access. Custom flashcard decks remain on the device; the User is responsible for their content and should have the rights required to use it.
8. Intellectual property and licence
Rights in the Application, Website, their code, layout, graphics, marks and databases belong to the Provider or relevant licensors. For the duration of the agreement, the User receives a non-exclusive, non-transferable licence, revocable where permitted by law, to use the Application for their own internal purposes and as intended. The licence does not cover sale, sublicensing, distribution, systematic database extraction or modification of the Application, except for acts expressly permitted by mandatory law. The User retains rights in custom-deck content.
9. Availability, updates and feature changes
The Provider may perform maintenance, fix defects, release updates, and change features to improve security, compliance, availability or development of the Application. Updates are distributed through the relevant store. Operation may be temporarily limited for technical or security reasons or because of an operating-system, store or hosting provider. The Provider may discontinue the free Application or Website with reasonable advance notice where possible. This section does not restrict mandatory User rights.
10. Termination
The User may stop using the Website at any time and terminate the Application agreement by uninstalling it. If mandatory law grants an additional withdrawal right, the User may exercise it by sending an unequivocal statement to the contact address. The Provider may terminate the agreement because of a material or repeated breach of these Terms or a legal requirement, subject to proportionality and consumer rights.
11. Complaints
A complaint concerning the Application or Website may be sent electronically to kontakt@kniazuk.dev or by post to the Provider’s address. To help resolve the matter, it is useful to include a description, occurrence date, Application version, device operating system and requested solution; data beyond what is needed for contact is not required. Complaints are considered without undue delay and no later than 14 days after receipt. This process does not restrict rights arising under mandatory law.
12. Liability
The Provider is responsible for supplying the services and for their conformity with the agreement under mandatory law. The Application is an educational aid and does not guarantee a particular learning outcome or completely error-free material. To the extent permitted by law, the Provider is not responsible for issues caused solely by an incompatible or defective device, an outdated system, User actions, or independent third-party outages. Nothing in these Terms excludes or limits liability that cannot lawfully be excluded in relation to a consumer.
13. Privacy
The processing of personal data and the storage of local data are described in the separate Privacy Policy.
14. Changes and final provisions
These Terms may be changed for a valid reason, in particular because of changes in law, features, service delivery, store requirements, or security needs. The current version is published at a permanent address. A material change affecting an ongoing agreement requires renewed acceptance in the Application; if the User does not accept it, they may stop using the Application. Polish law applies, but this does not deprive a consumer of protection granted by mandatory laws of their country of habitual residence. Disputes are heard by courts competent under applicable law. Information about out-of-court consumer dispute resolution is available at uokik.gov.pl. The English version is provided for accessibility; if versions differ, the Polish version prevails to the extent permitted by law.
15. Contact
Questions about these Terms or the services may be sent to kontakt@kniazuk.dev.
